KTX air condition circulation pump:As the requirements of environment have been improving in our country, the central air conditioning system has been applied extensively. As the key auxiliary equipment of central air conditioning system, the pumps have played important role in the safe, reliable running of system. Due to the peculiarity of pump in the application of center air conditioning system, many designers have made endless efforts for searching the ideal circulating pump --- big flow capacity, big power and high efficiency of pump operation; No leakage of pump in special working condition. Because the residents and staffs require the living and working environment to be quiet, pumps are required to run at low noise. The system with the relative pressure not only requires the pump body to have strong ability of anti-pressure, but also requires the pump body itself can balance the additional torque caused by the system. The construction owners require to reduce the area of pump house as small as possible, so that the installation space of pump should be small as possible, In conformity with the aim of "serve the society with high technical products, Lanshen Pumps Group has gathered many design concepts from the heating engineers; And fully analyzed and researched the engineering characteristic of typical air conditioning system, finally developed KTX type low noise air conditioning circulating pumps. The pumps can not only meet the special requirement of air conditioning system, but also bring great convenient to installation and commission of pumps, so the pumps are the first choosing products for heating engineering.

ApplicationAir conditioning and heating system Industrial cooling system be used for the water supply and the drainage of agriculture, factories, mines and city municipal.

Applicable Working ConditionFlow capacity: 1100m3/h (maximum) Head: 25- 50m Temperature of medium: ≤ 105º C Working pressure: 1.6MPa---2.5MpaSTRUCTURE DIAGRAMMaterial: · Pump body- High strength casting · Impeller- HT200(standard) bronze alloy (optional) · Anti-abrasion ring- Tin bronze · Shaft sleeve- 1Cr18Ni19Ti stainless steel · Shaft seal- Balance type mechanical seal The quality imported mechanical seals can ensure 18000 hours of running life and no leakage to occur. The high strength iron cast and CAD design can ensure the bearing parts of pump wouldn't deform under the pressure of 1.6MPa. While sustaining the great pressure of system, the vertical pipeline layout and the most outstanding base-plate design have made the outside torque acting on the pump casing to be small, so that the service life of isolating components in system are extended. The advantages of this kind pump are as follows: The outstanding hydraulic design, the stable performance, the running without disturbing, high efficiency, and the lowest hydraulic noise. Double suction impellers can effectively balance the axial force. The patent technology is adopted for the design of motor. The fan blades are cancelled. The adoption of self-circulating cooling water for cooling motor has greatly reduced the noise of motor. The international brand bearings are adopted and the grease is used for lubricating, so the maintenance is very easy. Within 50000 hours of safe operation, the part needn't replacing. The common motor can be used according to the requirement of customers. The extending motor shaft directly drives impeller.
